To all whom it may concern:

Be it known that we, MELVILLE BLBAIRD and GEORGE A. WALLS, citizens ofthe United States, residing at Kansas City, in the county of Jackson andState of Missouri, have in- ;vented certain new and useful Improvementsin Vending Machines; and we do dedlare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the ac-companylng drawings and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates I to coin-controlled vending machines andparticularly to a machine for vending paper cups capable for use atdrinking fountains and the like.

The invention contemplates the provision .of means whereby the papercups may'be contained within a receptacle and rendered inaccessibleunless a coin, check or token of authorized denomination is introducedinto certain novel ejecting mechanism, which constitutes one of thenovel features of our invention, there being means provided whereby theinsertion of an illegal coin, check or token through the discharge opening in the receptacle will cause the opening to be closed so that accessto the cups cannot be had.

In the drawings,

Fig. I is a perspective view of a vending device constructed inaccordance with our invention, parts being broken away to show theinterior construction thereof.

Fig. II is a fragmentary, vertical, longitudinal, sectional view of adevice embodying our invention.

Fig. III is a view, showing a part of the floor and a portion of theejector.

Fig. IV is a bottom perspective view of the ejector and thecoin-receiver inejecting position.

Fig. V is a similar view showing the ejector in cup-engaging positionand the coin being released.

Fig. VI is a detail view of one of the cups.

Fig. VII is a fragmentary, perspective fragmentary, perspective and,Fig. VIII, is a detail viewof the slotted guideon the ejector.

View of the jaw end of the ejector actuator,

swinging gate or door9, the inward swinging movement .of which is;adapted to be opposed by the stop 10, struck up. fromthe floor 3, asvshownin FigL III, sothat in the event that an. illegal T instrument .isforced through the slotted hood 8 from the exterior of the receptacle.its passage will be arrested by. the gate 9 although the ejection of thecups in an authorized manner, will not be seriously opposed.

The floor 3 of. he receptacle is shown providedwith a slot 11 over whichis adapt-v ed to slide an ejector bar 12 having an up,

wardly curved front end 13 and, a hooked end 14: at its rear, the parts13 and 14 being designed toengage parts of the cups. 7, as will appearhereinafter.

Suspended from-the bar 12 and'slidable along the under face of the floor3 is a plate 15 fastened to the bar between theedges of.

the slot 11 so the movements of the plate 15 and bar 12 will besynchronous. The plate 15, which constitutes part of the ejecting ordelivery device, isprovided' at one side edge witha verticallyextendingguide member 16 having a flange. 17 provided with a slot 18:through which a set, screw passes into the plate 15 whereby the guidemay beadjusted with relation to the plate. Bv reference to Figs. IV, Vand VIII it will be observed that the guide is provided with a lateralgroove 20. parallel with the slot 11 and that in the floor of the groove20 is a through slot 21 adapted to align with the coin slot 22, theinlet of which is at the front of the receptacle, as shown at 23, therebeing a return slot 24 provided in which is the; rear end of the guidewhen the bar- 26 y 26, the front end of which the 'frontpanel of thereceptacle and is provided with a stop pin 27. The rear end of the bar26 is cut away to provide a coin engaging jaw 28 of a lengthsubstantially the length of the slot 21 and adapted to registertherewith, but the rear end of the bar 26 extends beyond the rear end ofthe guide 16 and 'carr'ies'a stop shown as a cross pin 29 so that thestop may engage against is pulled out and therebycausethe ejector tomove Ito ejecting position. WVhen, however, the bar 26 is pushedinwardly, its movement will be independent of the guide unless opposedby a coin, check or token introduc'ed through the to be held in theguide by a coin support coin slot 22 adapted 30, carried by the plate15.

The coin support or retainer for the. coin receptacle is shown asconsisting of a lever pivoted to the plate 15 at 31 and normally urgedby aspring 32 to coin-releasing position but the spring will beopposedby a cam rail 33, along'the edge of which the arm 341maytrav'eltoward the end of the inward stroke ofthe bar 26am the ejector,Therefore, it will be seenv that when the cheek, coin or token isintroduced into the machine, it will pass into the slot 22 and dropiiito the receiver, passing partly through the lot 21 where its movementwill bearrested by the coin support 30. During this time the parts will"be in substan tially the position shown in F ig. IV. Up on a rearwardmovement of the bar 26 the jaw28will be caused to engage the coinbecause the coin will fill the gap between the movement has beensufficient to cause the a lever arm 34 to ride eff theedge 33, whereupon the spring 32 will urge the coin re .tainer 30 away from the slot21, permitting the coin to' d rop into the coin receptacle 5. Theejector nd its actuator thereupon become disconnected for movement inone di-f rection but the return movement, that'is, an outward movementof the bar 26 will cause the stop, shown as a cotter p'in'29,-to engagethe rear edge of the guide 16 so that the ejector and its actuator mustmove together in an outward direction or toward the slot 6. The movementof the ejectortoward the slot will cause the lip 13 to engage theoutwardly curled 513236 of p 7 and the upturned end 14L to engage theedge 37 of the cup 7 o that the cup will be moved up the spring stop 10,between it and the finger 38 and pass the outwardly opening gate 9 sothat its end will protrude through the slotted hood 8, whereupon itmaybe removed. i

It is to be'understood that the cups will be introduced into thereceptacle in stacks, the portions 36 extending downwardly andrearwardly so that the end 39 will be disposed toward the ejecting slotof the machine, enabling the cups to be easily engaged bytheslidel2. W 7

The ejection of the cup will be effective in bringing the plate 15 andits appurtenances to the front ofthe machine and it cannotyagain beretracted to, cup-engaging position unless the guide j-is oconnected tothe actuator 26 by another, coin, check or token of appropriatedenomination. Upon the presentation of a proper coin, the ejector andits actuator may again be locked together and the machine permitted ,tofunction. a 7 Iran unauthorized coin, check or token is inserted throughthe opening 23, the magnet 25 will deflect it to the return slot 24 sothat it will be returned to the customer.

WVhat we claim and desire to secure by Letters-Patent is p Incombination, an article container, a reciprocatory-ejector, a coinreceiver carried by the ejector, an ejector actuator having a part toabut against the coin receiver,.depending lugs adjacent to the coinreceiver. and spaced apart to provide guides, a. piv; otedmember havingone end Weighted and the other end movable between the lugs and normallylying in a position to obstruct the passage of a. coin through the coinreceiver, and means for tilting the pivoted member to release the coin.

In testimony whereof we aflix our signatures. v v I MELVILLE B. BAIRD;GEORGE A. WALLS.
